Chilly Winter Morning In Mumbai Later Covered With Smog, AQI Rises To 286

Mumbai residents woke up on Wednesday to a cool and refreshing winter morning, with clear skies and pleasant breezes. For a few hours, the city experienced a rare sense of freshness, as temperatures dipped to around 20°C, offering relief from the usual humidity.

However, the joy was short-lived. As the morning progressed, a thick layer of smog began to cover the city, blurring the skyline and reducing visibility. By mid-morning, the clean air had disappeared, and Mumbai was once again struggling under the weight of heavy pollution.

According to the India Meteorological Department (IMD), the city was expected to have a bright and mild day with maximum temperatures around 33°C, but rising pollution quickly overshadowed the forecast.

Air Quality Dips to 'Unhealthy' Levels

Data from AQI.in, an air quality monitoring platform, showed that Mumbai's overall Air Quality Index (AQI) reached 286, falling into the 'unhealthy' category. Health experts warned that such levels can cause breathing difficulties and worsen existing health conditions, particularly for children, the elderly, and people with respiratory or heart problems.

Doctors advised residents to avoid outdoor activities, especially in the early morning and late evening when pollution tends to peak. Masks, air purifiers, and staying indoors were recommended as short-term safety measures.

The poor air quality is largely linked to the city's ongoing construction boom. Mumbai is currently a massive worksite, with multiple metro lines, flyovers, road-widening projects, and real estate developments in progress. The dust and fine particles from these activities mix with vehicle emissions, especially during rush hours, worsening pollution levels across the city.

Wadala and Chembur Record 'Severe' Pollution Levels

Among all city areas, Wadala Truck Terminal emerged as the worst affected, recording an AQI of 362, which is classified as 'severe'. Close behind were Chembur (358), Bandra (352), Juhu Tara (349), and Govandi (341) - all falling in the 'severe' pollution range.
Suburban areas were slightly better but still unsafe.

Andheri East recorded an AQI of 107, while Powai and Kandivali East showed readings around 177. Borivali East and Bhandup West were also in the 'poor' category with 180 each.

As per air quality standards, AQI between 0-50 is 'good', 51-100 is 'moderate', 101-200 is 'poor', 201-300 is 'unhealthy', and anything above 300 is considered 'severe' or 'hazardous'.

Environmental activists have urged the Brihanmumbai Municipal Corporation (BMC) and Maharashtra Pollution Control Board (MPCB) to take stronger action, including dust control at construction sites and stricter checks on vehicle emissions, to prevent the city's air from becoming dangerous to breathe.
